The following seems to do it here:

mkdir /tmp/u{1,2}/w{1,2}
{pts/1}% zsh -f
cooker% autoload compinit; compinit
cooker% zmodload zsh/complist
cooker% zstyle ':completion:*' menu 'select=0'
cooker% bindkey -M menuselect "/" accept-and-infer-next-history
cooker% setopt menucomplete
cooker% zstyle ':completion:*' format Completing %d
cooker% ls /tmp/uTAB

Now you get menu selection; press two times '/' to get "Completing 
'files'" (at /tmp/u1/w1/ line contents); now press undo (^_) until you 
get empty line; press RETURN; press 'ls /tmp/uTAB'. Zsh crashes.

For some reasons crucial point is setting "format". Not only can I not 
make it crash without this; it seems to change the undo behaviour as 
well - pressing undo multiples times with and without "format" set 
cycles through *different* line contents.
